Green and Blue Laser Welding
Laser welding, cutting, or cladding has become increasingly popular and, in most cases, has been performed at the NIR wavelength region. However, NIR lasers are less efficient for copper processing due to high reflectivity and therefore low energy absorption. Copper absorbs just 5% of the laser energy at 1070nm, but up to 40 % at…

High Power Lasers – Just Measure It
Laser power and the applied laser densities are constantly rising. These high-power lasers are more likely to be used in materials processing applications such as welding, cutting, cladding, or additive manufacturing. Many of those applications are demanding: The laser’s focal spot and beam profile need to be kept within the specification to achieve the required…

Troubleshooting in SLM (Selective Laser Melting) systems with BeamWatch & BeamWatch AM
When asking the SLM manufacturers and users about what they need to know about the laser beam, the first answer we mostly get is, the cross section of the beam profile. But sometimes, this is not the key to solving most problems. The following blog post offers examples of additive manufacturing systems troubleshooting using Ophir’s…
